Nine Standards Rigg is the summit of Hartley Fell in the Pennine Hills of England. It lies near the boundary between Cumbria and North Yorkshire, a few miles south-east of Kirkby Stephen and approximately 770 yards (700 m) outside the Yorkshire Dales National Park. Nine Standards Rigg lies within the North Pennines Area of Outstanding Natural Beauty (AONB).[1] The name is derived from a group of standing stones or cairns, the Nine Standards, located near the summit. The fell is listed as Nine Standards Rigg, rather than Hartley Fell, in Alan Dawson's book The Hewitts and Marilyns of England.

The Nine Standards themselves, some of which were originally more than four metres high, are on the line of the Coast to Coast Walk between Kirkby Stephen and Keld, and are just to the north of the fell's summit. Situated at a height of 650 m, their original purpose is uncertain but one possibility is that they marked the boundary between Westmorland and Swaledale.[2]
